- 1What does FDE stand forFetch, Decode and Execute
- 2Clock speed per processorup to 100,000,000 per second
- 3Purpose of the CPU?To process instructions
- 4What size level is the cache for it to be very fast1, level 1 is very small and fast
- 5True or False : The bigger the cache, the slower it is.True
- 6What does CPU stand forCentral Processing Unit
- 7what is clock speed measured inHertz
- 8Clock speedThis is how many Fetch, Decode, Execute cycles the processor can
complete per second. - 9CacheA small high speed memory used to store frequently used instructions
from the CPU - 10Coresthe more cores you have, the faster it can process instructions
- 11CPUThe Central Processing Unit fetches, decodes and executes instructions.
- 12Control UnitWorks with the CPU to control the flow of data within the systems and
to decode instructions - 13ALUArithmetic Logic Unit carries out the calculations and logical decisions
within the CPU. - 14Name four registersAccumulator(ACC)
Memory Address Register(MAR)
Memory Data Register(MDR)
Program Counter(PC) - 15What does ROM stand forRead Only Memory
- 16What does ROM dostore the boot up instructions
- 17NetworkTwo or more devices connected together in order to communicate and share rescources.
- 18Nodea device connected to a network
- 19Packeta chunk of data that forms part of a message
- 20Hardwarethe physical part of a network
- 21RouterA device that sends packets between networks. It makes decisions about where to send data and by wehat route.
- 22WAP (Wireless access point)a device that allows deviceas to connect to a network with standards such as wifi and bluetooth
- 23SwitchFilters and forwards data packets directly to the intended recipient
- 24HubFilters and fowards data packets to all connected nodes.
- 25NIC (Network interface controller)A computer component that allows a computer to connect to a network
- 26Client Server NetworkMost common way to organise a LAN. One or more computers are designated servers.
- 27Peer to Peer NetworkAll computers are considered equal. Functionality can be divided between nodes. Each computer can act like a server.
